please help me..please.

这是我的Main_Activity.xml：

here is my Main_Activity.xml:

package com.example.torres;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_main);

    final EditText numbers =  (EditText) findViewById(R.id.editText1);
    final EditText results = (EditText) findViewById(R.id.editText2);

    Button btnConvert = (Button) findViewById(R.id.button1);     
    btnConvert.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick(View arg0) {
         String numberz =numbers.getText().toString();
         try {
             final long number = Long.parseLong(numberz);
             String returnz = Words.convert(number); 
         } catch ( NumberFormatException e) {
             //Toast.makeToast("illegal number or empty number" , toast.long)
         }

                       }  });


        }}

和这里是我的Words.java

and here is my Words.java

package com.example.torres;

import java.text.DecimalFormat;

public class Words  {




      private static final String[] tensNames = {
        "",
        " ten",
        " twenty",
        " thirty",
        " forty",
        " fifty",
        " sixty",
        " seventy",
        " eighty",
        " ninety"
      };

      private static final String[] numNames = {
        "",
        " one",
        " two",
        " three",
        " four",
        " five",
        " six",
        " seven",
        " eight",
        " nine",
        " ten",
        " eleven",
        " twelve",
        " thirteen",
        " fourteen",
        " fifteen",
        " sixteen",
        " seventeen",
        " eighteen",
        " nineteen"
      };

      private Words() {}


    public static String convertLessThanOneThousand(int number) {
        String soFar;

        if (number % 100 < 20){
          soFar = numNames[number % 100];
          number /= 100;
        }
        else {
          soFar = numNames[number % 10];
          number /= 10;

          soFar = tensNames[number % 10] + soFar;
          number /= 10;
        }
        if (number == 0) return soFar;
        return numNames[number] + " hundred" + soFar;
      }


      public static String convert(long number) {
        // 0 to 999 999 999 999
        if (number == 0) { return "zero"; }

        String snumber = Long.toString(number);

        // pad with "0"
        String mask = "000000000000";
        DecimalFormat df = new DecimalFormat(mask);
        snumber = df.format(number);

        // XXXnnnnnnnnn
        int billions = Integer.parseInt(snumber.substring(0,3));
        // nnnXXXnnnnnn
        int millions  = Integer.parseInt(snumber.substring(3,6));
        // nnnnnnXXXnnn
        int hundredThousands = Integer.parseInt(snumber.substring(6,9));
        // nnnnnnnnnXXX
        int thousands = Integer.parseInt(snumber.substring(9,12));

        String tradBillions;
        switch (billions) {
        case 0:
          tradBillions = "";
          break;
        case 1 :
          tradBillions = convertLessThanOneThousand(billions)
          + " billion ";
          break;
        default :
          tradBillions = convertLessThanOneThousand(billions)
          + " billion ";
        }
        String result =  tradBillions;

        String tradMillions;
        switch (millions) {
        case 0:
          tradMillions = "";
          break;
        case 1 :
          tradMillions = convertLessThanOneThousand(millions)
             + " million ";
          break;
        default :
          tradMillions = convertLessThanOneThousand(millions)
             + " million ";
        }
        result =  result + tradMillions;

        String tradHundredThousands;
        switch (hundredThousands) {
        case 0:
          tradHundredThousands = "";
          break;
        case 1 :
          tradHundredThousands = "one thousand ";
          break;
        default :
          tradHundredThousands = convertLessThanOneThousand(hundredThousands)
             + " thousand ";
        }
        result =  result + tradHundredThousands;

        String tradThousand;
        tradThousand = convertLessThanOneThousand(thousands);
        result =  result + tradThousand;

        // remove extra spaces!
        return result.replaceAll("^\\s+", "").replaceAll("\\b\\s{2,}\\b", " ");}




      }

唯一的问题是现在不会发生什么意外笑

The only problem now is that nothing happens lol

推荐答案

您可以单独类的 EnglishNumberToWords 如示例中的链接。

You can make separate class for EnglishNumberToWords as in the example link.

和在你点击链接，你必须只需拨打

and in your button click you have to just call

String return_val_in_english =   EnglishNumberToWords.convert(YOUR_NUMBER_TO_CONVERT);
